I dropped small stainless nut just like that. But when I dropped it went into ocean, because I was working on friends 38ft Bayliner, over water. To make me feel even worse, we had to drive back to town for a replacement! Man!
I thought I had dead battery at Cabela's parking lot. Customers say, we'll push you to get started. An engine started with little effect. But my battery was fried when I got home, finding cause of problem not dead battery but rectifier failed to convert 110V into 12V. My battery was fried because it was injected with 110V all way home, instead of usual 12V. Now I'm learning about rectifiers, buying new battery as well as new rectifier. My thoughts, you should find out what's really wrong before just push starting bike an riding it home?
The AC voltage seemed a bit high. I would of reved the motor a bit to see how high it went at like 3k rpm. If it was any higher than 46v ac I would think that is causing premature failure in the R/R rectifier/regulator and overcharging battery causing premature failure of the battery as well. Well done I soldier everything!😂
No. You really can't test the regulator. If your stator is putting out proper voltage but the battery isn't getting proper voltage, then you can figure it's the regulator.
While that reading is more than the book recommends, it doesn't mean it's bad. Turn your meter to AC volts and start the engine to see what the alternator is putting out. You should see an output of about 20 volts per 1000 rpm.
I'm not sure I understand what you are saying. The bike will run off just the battery for some time. You need a working voltage regulator to convert the stator output from AC to DC voltage. The wire from the regulator to the battery goes to a breaker, not a fuse. Breaker should have battery voltage on both sides even without the bike running.
Best video of any I've watched.

Nicely done and thanks for posting...I learn something new every time!

Is there an easy test for the regulator itself? And thank you for your very clear video.

@@WitchcraftCycleWorks Thank you sir!
That is the exact problem I'm having, and I didn't catch it's quick enough and boiled my battery
I'm getting 00.7 to 00.8 resistance when testing the stator on my 1992 Fatboy is that a bad stator?

@WitchcraftCycleWorks thank you I'll be doing that today.
Bike runs without voltage regulator, stator good, this bike doesn't have power to fuse / terminal.
